Trump's Energy Secretary just confirmed it: this regime knew exactly how its war of choice with Iran would hurt Americans, force gas prices to skyrocket, and put the global economy at risk.
We've all seen the videos of ICE pulling people out of their cars, shooting citizens with pepper balls, and even worse killing Americans in the streets. This is not normal. And it cannot continue. ICE needs commonsense guardrails NOW.
Our elections are ALREADY safe and secure. Republicans know that. But they also know that Americans are unhappy with their chaotic agenda. So instead of helping their constituents, they'd rather perpetuate lies about fraud to justify making it HARDER to vote them out of power.
ICE is killing American citizens in the streets, violently pulling people out of their cars, shooting them with pepper balls, all while the death toll of individuals in ICE custody grows — and Republicans want to give MORE funding to ICE? ICE needs reforms. Not a blank check.
Trump's illegal war with Iran is costing U.S. taxpayers BILLIONS, has left 13 U.S. servicemembers dead, killed thousands, weakened U.S. credibility, and is forcing prices here at home to skyrocket — and Senate Republicans are doing nothing to stop it. Spineless.
$1,000,000,000,000 This regime's unauthorized war with Iran could cost U.S. taxpayers up to $1 TRILLION. $1 TRILLION — with a "T". All while they claim there isn't enough funding for health care, food assistance, education programs... Republicans' priorities are beyond wrong.
Someone is dying in ICE custody EVERY WEEK. And that doesn't even include the American citizens ICE has killed in the middle of our streets in broad daylight. It could not be more clear, ICE needs guardrails, not a blank check from Congress.
A temporary “ceasefire” was negotiated, yet bombs are still flying, the Strait of Hormuz remains effectively closed, and the death toll tragically continues to rise. This regime owes Americans answers on what the hell is going on. How are they going to end this war of choice?
On AANHPI Equal Pay Day, it’s important we recognize that the wage gap persists for AANHPI women.   Today, we must acknowledge how harmful and prevalent these inequities are in the workplace, and reaffirm our commitment to securing gender pay equity.
15 people have died in ICE custody JUST THIS YEAR. That is 1 death a week. Under this regime, 2026 is set to be the deadliest year for ICE detention EVER. The need for guardrails and meaningful oversight could not be more urgent.
We have the numbers to prove it. This regime cares more about funneling BILLIONS of YOUR taxpayer dollars into an unauthorized war than they do about taking care of our veterans or your ability to afford health care, groceries, energy, or housing. It's diabolical.
Trump has no plan to reopen the Strait of Hormuz. Out of desperation, he's now making an existential threat to Iran.   Trump CANNOT & WILL NOT wash his hands of the cruelty and chaos he has sowed for MILLIONS of people across the country and around the world.
Trump started this illegal war with no plan. And instead of trying to end it, he’s now threatening MILLIONS of innocent Iranians, not just Iran’s military or senior leadership. It's beyond barbaric.
Trump’s illegal war in Iran has already killed American servicemembers & innocent civilians. Gas prices are sky-high and now, Hawaii families will see their power bills rise from between $40–70/month. The costs of Trump’s reckless decision to start this war keep growing.
The 14th Amendment is clear—"All persons born or naturalized in the United States...are citizens of the United States..." Just because Trump doesn’t believe in the Constitution, doesn’t mean he can ignore it. I expect SCOTUS to do its job and check Trump’s reckless abuse of power.
